Yam Songgou machine is popular with vegetable farmers.

Why does the yam loose ditch machine be welcomed by vegetable farmers, and what advantages does it have? First of all, the use of loose ditch machine can ensure that the depth of yam ditch is consistent, and more labor and time saving. When the Chinese yam trencher is used for digging Chinese yam trenches, as long as the loosening depth of the chain wheel is fixed after the loosening chain wheel is drilled into the ground, the soil can be loosened from one end of the trench to the other end of the trench, and the situation that the trench depth is different due to the digging of the small excavator does not occur. Secondly, it is beneficial to the growth of yam. After the furrow loosening machine is used for loosening the furrow, the soil in the furrow has the same degree of looseness from top to bottom, which is more beneficial for the root system of the Chinese yam after planting, promotes the growth of the root group of the Chinese yam, and simultaneously reduces the bending probability of the Chinese yam tuber due to external resistance in the downward growth process. However, the small excavators often used by vegetable farmers could not crush all the soil blocks when digging yam ditch backfill soil, resulting in inconsistent soil porosity and easy bending of yam tubers. Therefore, the small excavators commonly used in the past were gradually replaced by yam loose ditch machines.
